Forget about Hell - Do you want to go to Heaven, or not?

Threats of Hell ("...if you carry on the way you are going") are useless at best, more often counter-productive, nowadays. 

This seems like a solid fact to me; the only uncertainty is exactly why (and there are almost certainly several, interacting, reasons for it). 

The Big Problem - which, I think, has never been anything-like so common in history - is not that people don't believe in Heaven; but that they don't want it - even if they could (somehow) know Heaven was true, and that they could go there after death.
